Original version of gar2rnx was developed by Antonio Tabernero Galan.
He discovered how to make Garmin GPS receiver sending raw GPS data, deciphered it
and made a program converting it to standard RINEX format.Click here to read more about it and to download
original, non-Java gar2rnx suite.

Antonio's software works ok, but it's an executable for Windows and Linux.
So, you need a PC computer in terrain during GPS survey. And that's a problem
because notebook computers are not very usable when used outdoor.
I thought it would be good to have the same capabilities on my palmtop computer,
but I didn't want to be bound to one specific type, so I decided to port gar2rnx
software to Java language. That way it could be possible to use gar2rnx / Java on
almost everything: from Unix workstation to smart cellular phone (like Nokia 9210).
And, of course, on palmtop.
